STOVE-PIPE.

SPECIFICATION forming part of Letters Patent 293,893, dated- February A19, 1884.

Application tiled August 24, 1883. l(No model.) l

all whom, it may concern: 4

Be it known that we, JAcoB Z. LINDLEY and JOHN V. ELDER, citizens of the United States, both residing at Lamar, in the county of Barton and State of Missouri, have invented new and useful Improvements in Stove-Pipes, of which the following is a specification.

Our invention relates to improvements in pipes or tubes for conducting away the smoke'v and products of combustion from stoves and other similar devices; and the object is to inspecification and the drawingsannexed, which -form part of .the specification.

Referring to the drawings, Figure 1 is a sectional view; and Fig. 2 a plan of three sections of pipe with our improvements applied thereto, shown in position ina thimble supported in a stove-pipe hole. Figs. 3, 4, 5, and 6 are detail views separately;

In each of the views similar letters of reference are employed to indicate corresponding ,parts wherever they occur.

A represents a portion of the briclcworkof a flue, and A the stovepipe hole leading to the iiue. i

B is a thimble, formed by preference of wrought sheet-iron, to the inside of which is riveted internally, toward Vits end b, one or more straps of metal, B, which are bent down behind the brick-work A, as shown in Fig. 1, for the purpose of preventing the withdrawal of the thimble B from the hole A.

C, C', and C2 are three sections of pipe, which are held in position by means and'in the manner hereinafter to be fully explained. rlhe sections C we have shown .connected to the thimble B by means of a strap, D, which at one end is hinged to the inside ofthe thimble B, as clearly shown at x, Fig. 2, in dotted line, where the end d3 is inserted into a slot in B and bent over, while its opposite end is provided with a slot, d, through which and a hole sired, by means of a nut, E. The sections C and C areshown connected together by a strap, D; but in this case the strap is not tion O, while its other end, slotted at d, is ar.- ranged to slide on ascreW-bolt passing through a hole in the section C and said slot d. The bolt E is retained in position by a screw-nut, E. The sections C and G2 are also connected together by the strip D 5 but in this case the strip is provided at one end with an upturned portion or handle, dii for the purpose of sliding it to and fro as desired. At its front end this strap D is formed with a returned spring portion, d', which in plan we prefer to be of to take' the form of a double incline, as shown in Figs. 1 and 2, leaving an elevated portion, d2, at the junction of the two in'clines. When section C, the strap D is pushed forward into This having been done, theend of the strap willr then protrude beyond the small end c of the section C', andmay readily be inserted with the small end c within the larger end of the section C. This having been done, the strap or extension D is drawn back by means of the handle d' into the position shown by full lines in Fig. 1, when the double -inclined spring portion d will be brought so vthat its pointed end d3 and elevated portion cl2 are jammed between the exterior of the small end c of the section O and the interior of the large end c2 of the section O,- thereby forming a. wedgeshaped abutment, whichwilliirinlyhold strap or extension D has been drawn so that its end d is in position to bind the parts C C together, as described, the same is secured by tightening the nut f.F/ and binding the strap D in position, Where it will 'remain until the nut E is again loosened for the purpose of re moving or adjusting the section. The sections C and C are shown connected together by a slotted strap or extension, D, similar to that shown for the purpose of'connecting the section C with the thimble B. In this case, however, in -place of being hinged, it is shown riveted to the section O and engaging with a hinged, but is fixed at one end upon the seca pointed shape, and inside view and section` it is desired toconnect the section C to the j in the small end c of the section C is passed a I, A* screw-bolt, E, which is held tightly, when dethe position shown by dotted lines in Fig. 1.

lOO

bolt and nut E E, carried bythe section C. l tension provided with a wedge-shaped end The strap D in this case, as will be seen7 is arranged on the exterior of the sections.

Although We have only shown three straight sections of pipe connected together according to our invention7 we can with equal facility use it for bent or curved sections or elbows.

rlhe strap D, attached to thiinble B, I prefer to be hinged7 in order that in summer time when a stove is removed the strap D will fall. as indicated by dotted lines, so as to allow of the application of a iiue-stop.

Having thus described our invention, what we claim7 and desire to secure by Letters Patent, is-

1. The combination, with a pair of sections of stove-pipe. of a sliding slotted strap or exi'or the purpose of holding the said sections in position, substantially as and for the purpose described.

2. The combination, with a pair of sections of stove or other similar pipe, of a sliding slotted strap held in position by a bindingscrew or equivalent nieans, and provided with an inclined spring extension or wedge7 substantially as shown and described.

In witness whereof We have hereunto set our hands this 4th day of June, 1883.
